• Octagonal eight-point body with 110mm across flats.
• Zinc-plated metal construction for grease-filled BPW wheel ends.

Why Choose ICS Trailers

Old-generation BPW caps can resemble later styles while using a different thread pitch and hub arrangement. Compare the M125 x 3 external thread, 110mm across-flats shape, 116mm ID and 83mm depth with the removed cap. ICS Trailers can use those measurements, old markings and axle details to narrow down the correct version.

• Support identifying the matching grease seals and seal carrier for the same wheel-end repair.
• Help compare genuine and aftermarket replacement numbers when old markings are incomplete.
